Abstract

La présente invention concerne un générateur de signal et un décodeur pour signal à étalement de spectre à bande latérale unique. Elle concerne un générateur de signal à étalement de spectre à bande latérale unique et un décodeur au moyen desquels on obtient une modulation à bande latérale unique, en utilisant un code à étalement complexe, avec des propriétés de corrélation améliorées, de façon à ce que l'interférence entre utilisateurs soit réduite.
